On Sight is a permanent video/sculptural installation by Connolly Cleary for Lough Lannagh in County Mayo exploring binocular vision, designed in consultation with le Laboratoire Psychologie de la Perception in Paris. Each of the four binocular viewing posts will be installed in situ on the lakeside in Spring 2012. The project is a public commission for Mayo County Council, part of the Landmark public art programme.
